Wiig hit all the right notes, but unfortunately she didn’t hit all the right words. The actress struggled with the pronunciation of “hallelujah.”

Noticing her inability to sing the chorus, Corden tried to teach how to pronounce the word correctly. At first she struggled, substituting the word with “holly-doo-dah,” “Halle Berry,” and “Hickory Farms.”

Eventually, Wiig got the gist of the word, and the two made beautiful music. That is until the gospel choir backed them up.

Apparently Wiig had “warmed them up” prior to the performance. So instead of singing “hallelujah,” they sang, “Hello, Julia.”

It was all too much for Corden, who opted to go to commercial break.

The Late Late Show With James Corden airs weeknights at 12:37 a.m. on CBS.
